Pre Update Notes
- This update may break some of your Monterey functions. Make sure you backup first. :thumbup:

Note: Before you update:
- Clover users must first disable or remove BlueToolFixup.kext in order to update. Otherwise the software update doesn't initialize it crashes System 'Settings'.
- make sure your USB ports are properly mapped. I recommend you use this procedure:

Here's the step by step way to update OC:
- Make sure you use the latest versions of the Lilu.kext, AppleALC.kext and WhateverGreen.kext.

Backup your current installation using Carbon Copy Cloner or SuperDuper;

Update to the latest Clover or OpenCore 0.8.6 or newer.
See the tonymacx86 Clover Builds (in Download menu) to update Clover. To update your OpenCore, see this guide. To convert from Clover to Open Core, see this guide.
:ch: Download OCAuxiliaryTools (OCAT):
:ch: Follow the OCAT Guide:
:ch: After completing the Update, reboot.
:ch: Upon reaching the Desktop, open the Terminal and execute:
nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version
Confirm you have updated OC to 0.8.6 or newer.

Download the Monterey 12.6.2. Update from Apple's Mac App Store using System Preferences > Software Update, and run it - the updater will reboot upon completion.
Note: Update will reboot three times; each time Clover/OpenCore picks the correct boot partition. So, sit back and relax. The update takes 3 reboots and ~30 minutes to complete.​

Done! So far, another easy update!

I did the 12.6.2 update without any problems with 3 reboots. I have OC 0.8.7 and the latest kexts.

Hello gents (and ladies in case :)),
just completed the update to 12.6.2 for my Dell XPS 15 9570.
Three reboots as usual, about 37 minutes for the entire process, including the download time.
OC version is 0.7.4.
A full clone by Super Duper has been saved on my WD 4TB USB disk in case of failure.

So far so good.

Installed 12.6.2 on my Big Red Z490 i9-10850 running OpenCore 0.8.5. About 25 minutes I think. There were the typical 3 reboots however one had a long black screen until the progress bar appeared (which was a bit nerve racking.) All seems to be running ok.
